When the test tube position sign test-tube rack that the counter was makeed statistics of has got into the test-tube rack and fed the district, the bar code of establishing is pasted on the scanning test tube to the scanner subassembly to discernment test tube, this test tube is got and is put back the test-tube rack after the mixing to the mixing subassembly clamp, then, the sample subassembly is inhaled to this test tube and is told sample and/or antibody, after final sample subassembly had absorbed sample and antibody, transversely advance the appearance subassembly and transport the test-tube rack to the test-tube rack uninstallation district, the uninstallation subassembly will be located the test-tube rack uninstallation of test-tube.

The manual sample introduction process of the specific protein analyzer is as follows:

place the test tube under the sampling needle of sampling subassembly, ensure that the sampling needle inlet is below the sample liquid level, trigger key switch 6, the sample and/or antibody are inhaled and spit to the sampling subassembly, and sample and antibody have been absorbed to the final sampling subassembly.

After the automatic sample introduction or the manual sample introduction of the specific protein analyzer is completed, the sampling assembly spits the absorbed sample and the antibody into the reaction cup, the liquid adding assembly adds the reagent into the reaction cup, after the stirring motor drives the magnetic bar stirrer in the reaction cup to stir, the laser emits laser to the reaction cup, the photoelectric conversion plate receives scattered light transmitted by the reaction cup, an electric signal containing a test result is generated and transmitted to the control card plate, the electric signal is displayed on the display screen, and the test process is completed at the moment.

Referring to fig. 9, another embodiment of the present invention provides a method for testing a specific protein analyzer based on the foregoing embodiments, the method comprising:

step S1: the sampling assembly spits the diluted sample and the antibody to the reaction cup group;

step S2: and after the preset time, the reaction module acquires data. The data is the test result, which includes CRP value, SAA value and SAA/CRP ratio.

Referring to fig. 10, in step S1, the method for spitting the diluted sample and the antibody to the reaction cup set by the sampling assembly specifically includes:

s11: the sampling component sucks a sample in the test tube;

s12: the sampling assembly moves to a pre-dilution position and spits a sample;

s13: the sampling component moves to the antibody position to absorb the antibody;

s14: the sampling assembly returns to a pre-dilution position to absorb the diluted sample;

s15: the sampling assembly moves to the reaction cup group to spit out the sample and the antibody;

s16: stirring the antigen and antibody in the reaction cup group.

Compared with the prior art, the specific protein analyzer and the test method based on the specific protein analyzer provided by the embodiment of the invention have the advantages that the automatic sample injector is configured, and the test tube rack placed in the sample feeding area of the test tube rack is transported to the sample feeding area of the test tube rack by the automatic sample injector, so that the specific protein analyzer capable of automatically injecting samples is realized.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; within the idea of the invention, also technical features in the above embodiments or in different embodiments may be combined, steps may be implemented in any order, and there are many other variations of the different aspects of the invention as above, which are not provided in detail for the sake of brevity; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
